Iphutha elijwayelekile 17: Lezi zimpawu zebhasi zonke zidonswa ngabaphikisi, ngakho-ke ngizizwa ngikhululekile.
Isixazululo Esihle: Kunezizathu eziningi zokuthi kungani izibonakaliso zidinga ukudonswa phezulu naphansi, kodwa hhayi zonke ezidinga ukudonswa. Ukudonsa nokudonsa phansi ukumelana kudonsela isiginali yokufaka elula, futhi okwamanje kungaphansi kwamashumi ama-micromples, kepha lapho kudonswa isiginali esiqhutshwayo, okwamanje kuzofinyelela ezingeni le-milliamp. Uhlelo lwamanje luvame ukunama-bits angama-32 wedatha yekheli ngalinye, futhi kungenzeka kube khona uma ibhasi eliqhelile lama-24/4 / amasiginali adonswayo, ungasebenzisi imiqondo yama-wattos angama-80 ukwelapha lawa ma-watts ambalwa wokusebenzisa amandla, isizathu sokubukeka phansi).
Iphutha elijwayelekile 18: Uhlelo lwethu lunikwa amandla ngo-220V, ngakho-ke akudingeki sinakekele ukusetshenziswa kwamandla.
Isixazululo Esihle: Idizayini yamandla aphansi ayona kuphela yokonga amandla, kepha futhi nokunciphisa izindleko zamamojula wamandla nezinhlelo zokupholisa, kanye nokunciphisa ukuphazanyiswa kwemisebe ye-electromagnetic nomsindo we-thermal ngenxa yokuncishiswa kwe-chariation yamanje. Njengoba izinga lokushisa ledivayisi liyancipha, impilo yedivayisi yanwetshwa ngokulandelana (lokushisa okusebenzayo kwedivaysi ye-semiconductor inyuka ngamadigri ayi-10, futhi impilo ifinyeziwe ngesigamu). Ukusetshenziswa kwamandla kumele kubhekwe nganoma yisiphi isikhathi.
Iphutha elijwayelekile 19: Ukusetshenziswa kwamandla kwalezi zinhlamvu ezincane kuphansi kakhulu, ungakhathazeki ngakho.
Isixazululo Esihle: Kunzima ukunquma ukusetshenziswa kwamandla kwe-chip engaphakathi okuyinkimbinkimbi kakhulu. Kunqunywa ikakhulu yi-PIN yamanje. I-ABT16244 idla okungaphansi kwe-1 ma ngaphandle komthwalo, kepha inkomba yayo yiphini ngalinye. Kungashayela umthwalo we-60 ma (njengokuqhathanisa ukumelana kwamashumi amashumi ama-ohms), okungukuthi, ukusetshenziswa kwamandla okuphezulu komthwalo ogcwele kungafinyelela kuma-60 * 16 = 960m. Vele, kuphela ukunikezwa kwamandla kwamanje kukhulu kakhulu, futhi ukushisa kuwela umthwalo.
Iphutha elijwayelekile 20: Ungabhekana kanjani nalezi zibuko ezingasetshenziswanga ze-I / O e-CPU ne-FPGA? Ungayishiya ingenalutho futhi ukhulume ngakho ngokuhamba kwesikhathi.
Isixazululo Esihle: Uma amachweba e-I / O engasetshenziswanga ashiywe entantayo, angaba amasiginali wokufaka aphindaphindwayo ngokuphazanyiswa okuncane kusuka ezweni langaphandle, futhi ukusetshenziswa kwamandla kwamadivayisi we-MOS ancike kwinani lamaphaphu wesifunda sesango. Uma kudonswa phezulu, i-PIN ngayinye izophinde ibe ne-microampere yamanje, ngakho-ke indlela engcono kakhulu ukuyibeka njengokukhipha (vele, azikho ezinye izibonakaliso zokushayela zingaxhunyaniswa ngaphandle).
Iphutha elijwayelekile 21: Kuneminyango eminingi kakhulu eshiywe kule FPGA, ukuze ukwazi ukuyisebenzisa.
Isixazululo Esihle: Ukusetshenziswa kwamandla kwe-FGPA kulingana nenani lamaflip-flops asetshenzisiwe kanye nenombolo yamaphaphu, ngakho-ke ukusetshenziswa kwamandla kohlobo olufanayo lwe-FPGA emibuthanweni ehlukene nezikhathi ezihlukile kungahluka kaningi. Ukunciphisa inani lamaflip-flops okuphelelwa ngejubane eliphezulu kuyindlela eyisisekelo yokunciphisa ukusetshenziswa kwamandla kwe-FPGA.
Iphutha elijwayelekile 22: Imemori inezimpawu eziningi zokulawula. Ibhodi lami lidinga kuphela ukusebenzisa i-OE futhi nathi sibonisana. Ukukhetha i-chip kufanele kusekelwe, ukuze imininingwane ivele ngokushesha okukhulu ngesikhathi sokufunda okufundwayo.
Isixazululo Esihle: Ukusetshenziswa kwamandla kwezinkumbulo eziningi lapho ukukhetha kwe-chip kuvumelekile (kungakhathalekile ukuthi u-OE futhi thina) uzoba ngaphezulu kwezikhathi eziyi-100 kunesiphi izikhathi eziyi-100. Ngakho-ke, ama-CS kufanele asetshenziselwe ukulawula i-chip ngangokunokwenzeka, futhi ezinye izidingo kufanele zihlangatshezwe. Kungenzeka ukunciphisa ububanzi be-chip khetha Pulse.
Iphutha elijwayelekile 23: Ukunciphisa ukusetshenziswa kwamandla ngumsebenzi wabasebenzi be-Hardware, futhi awuhlangene ne-software.
Isixazululo Esihle: I-Hardware isiteji nje, kepha isoftware ingumlingisi. Ukufinyelela cishe kwawo wonke ama-chip ebhasini kanye ne-flip yawo wonke amasiginali cishe asuswa yi-software. Uma isoftware inganciphisa inani lokufinyelela kwimemori yangaphandle (kusetshenziswa ukuguquguquka okuningi kwerejista, ukusetshenziswa okwenziwe ngesikhathi okuphezulu, nezinye izindlela zokuphazamiseka (iziphazamiso zivame ukusebenza kakhulu ngamabhodi okudonsela phansi konke azonikela kakhulu ekunciphiseni ukusetshenziswa kwamandla. Ukuze ibhodi liphenduke kahle, i-Hardware ne-software kumele zithathwe ngezandla zombili!
Iphutha elijwayelekile 24: Kungani lezi zimpawu zibhema ngokweqile? Uma nje umdlalo ulungile, ungaqedwa.
Isixazululo Esihle: Ngaphandle kwezimpawu ezimbalwa ezikhethekile (njenge-100base-t, cml), kukhona ngokweqile. Uma nje kungabi kukhulu kakhulu, akudingeki ukuthi kufaniswe. Noma ngabe kufana, akufani nakancane. Isibonelo, imiphumela yokukhishwa kwe-TTL ingaphansi kwama-50 ohms, namanye ama-ohms angama-20. Uma ukumelana okukhulu okufanayo kusetshenziswa, okukhona manje kuzoba kukhulu kakhulu, ukusetshenziswa kwamandla ngeke kwamukeleke, futhi i-amplitude yesiginali izoba incane kakhulu ukuba isetshenziswe. Ngaphandle kwalokho, okukhishwayo kokukhishwa kwesiginali ejwayelekile lapho kuphuma izinga eliphakeme kanye nokuphuma okuphansi akufani, futhi kungenzeka futhi ukufeza ukufana okuphelele. Ngakho-ke, ukufana kwe-TTL, ama-LVD, ama-422 nezinye izibonakaliso kungamukeleka inqobo nje uma i-Overshoot itholakala.
